Altiris Inventory and NTFS mounted drives support

Altiris inventory does not report Windows mounted drives in reports with version 6.5.  Does anyone know if this is available in 7?

This is output from an in-house utility:

Label   Letter  Free%   Free MB         Used MB         Size MB
BOOT    C:      23%     2,410           7,662           10,072
APPS            15%     3,424           19,073          22,497
HOME            34%     137,232         255,984         393,216
DATA    D:      9%      94,564          888,473         983,037

APPS is actually mounted on D:\Apps
HOME is actually mounted on D:\DATA\USERS

Altiris Logical Disks shows I have a C: drive and a D:\ drive of 983 GB.  It does not count the APPS and HOME volumes.

The physical disks will show all physical disks but I only get the total size, not usage.  Also the volumes don't always correspond to one physical disk.
